Cytinus is a genus of parasitic flowering plants. Species in this genus do not produce chlorophyll, but rely fully on its host plant. Cytinus usually parasitizes Cistus and Halimium, two genera of plants in the family Cistaceae. It has also been found on Ptilostemon chamaepeuce.

Several species are found in the Mediterranean Region, South Africa, with a possibly undescribed species from Madagascar.[1]
Biology
editC. capensis and C. sanguineus are dioecious, while C. hypocistis is monoecious.[2]
C. hypocistis has been shown to infect mainly Halimium halimifolium and Cistus monspeliensis in Portugal.[3]
Systematics
editThe genus Cytinus was previously included in the parasitic family Rafflesiaceae, but is now put into the family Cytinaceae[2] (order Malvales), together with the genus Bdallophytum with four species.
Cytinus ruber is no longer considered a separate species, but is now a subspecies of C. hypocistis.
Uses
editThis article needs more reliable medical references for verification or relies too heavily on primary sources. (November 2014) |  |
The young C. hypocistis is cooked as an asparagus substitute and an extract has been used in herbal medicine for dysentery, throat tumors and as an astringent.[4] C. ruber is also edible and was used in folk medicine as an emmenagogue.[5]
